The invention discloses a high-resolution intelligent network camera array system with global synchronization function. The system adopts global synchronization signals to realize the synchronous acquisition of a camera array, comprises at least two intelligent network cameras used for image acquisition, wherein the working mode of one camera is configured as a main mode, while the other cameras are configured to be in a slave mode; the main-mode camera produces and provides global horizontal synchronization signals and vertical synchronization signals for the slave-mode cameras; and every intelligent network camera is connected with a central computer through a network and is used for receiving control commands in real time and transmitting image data so as to realize distributed computing function. The system has the advantages of satisfying the real-time high-performance processing for acquired data, realizing the global synchronous shooting of the camera array, supporting large-scale array expansion, realizing the control of the central computer over a plurality of working modes of the intelligent cameras and realizing high-resolution video-image data shooting.

Description

technical field [0001] The invention relates to the application field of multi-cameras, in particular to a multiple high-resolution network camera array system capable of realizing the global synchronous shooting function. Background technique [0002] At present, no matter in the field of research or in practical application, video image processing puts forward higher and higher requirements for data acquisition and processing systems. These requirements include image quality, processing operation, synchronous acquisition, remote control, network transmission, system cost and many other aspects. [0003] In particular, in 3DTV, stereo vision, and 3D reconstruction, during the calibration, registration, and depth acquisition of images captured by multiple cameras, the camera array needs to be captured synchronously from multiple angles and different positions to enrich the two-dimensional image of the object. Therefore, the synchronous shooting of the camera array is partic...

Problems solved by technology

Most of the current synchronization technologies require external signal triggering or inserting time stamps into the data. The former not only requires a dedicated signal generator, the hardware implementation is complex, and the integrity of the synchronization signal also limits the scale of the camera array.

The latter increases the complexity of synchronous software design and subsequent image processing procedures, and because the processor subsystem will be affected by processor interrupts or other processes when receiving image data, when each video is independently collected, the received Data time numbers the image frames, prone to loss of synchronization in the processor
